Fig. 1 is an elevation of a door embodying the width of the door, and are connected by riveting a novel features in one form; Figs. 2 and 3 areirag'- thereto. Thelsection bars I2 serve for xing pro-A mentary side views of two bars included in this tecting edges or buffersZU consisting of rubberor form; Figs. 2a and 3a are cross-sections of the rthe like. The angular bends 2l on the` bars I2' 555':

form alone a gauge for the parts l and 2 of the door to be clamped therein, which considerably facilitates the exactitude and rapidity of the assembling of the door halves. The window frame 22 is inserted in the angle bars I9. This window frame has, for example, an S-shaped section and on inserting is pushed with one longitudinal edge according to the position shown in broken lines in Fig. 7 over rivet heads 23 projecting further forward on the window aperture and then deflected into this, whereupon from the front edge of the door screws 24 with bolt-like extensions 25 are screwed in front of the cross bar of the window frame located on this side of the window aperture, which without anything else hold all the parts in the position of use without any means of fastening being visible, and all the abutting edges on the window aperture being covered in the manner of a frame. Instead of the S-shaped section, a different suitable profile may be used. Y

The fixing of the door handle 23 takes place according to Fig. 8 by conical members 2l being inserted in conical holes or recesses 28 of an intermediate part or section 29 and being fixed by screws 30 which engage from the outer edge of Ythe door by means of a bolt-like conical part 3| in a transverse hole 32 of the piece 2. The slide guide bars 33 on the faces of the door are inserted by pins 34 in the manner of a bayonet joint in holes 35 covered by the bars 33, and after pushing in the longitudinal direction are fixed by a screw 36 inserted from the edge of the door and which bears with a projection 31 against overlapping inwardly directed lugs 38 of the bars 35. The upper and lower edges of the door are closed by U-shaped bars or channel members 39, 40 which also form a gauge for the parts I and 2 of the door to be clamped therein, and which are clamped round by the U-shaped bar cross pieces. There are provided as shown in particular by Figs. 12 to 14, at the upper corners of the door insets 4| which by means of a projection 42 and rivets 43, are xed on the U bars 39,40 and by a rivet 44 on the longitudinal side of the door. The door lock can be fixed in one or more recesses 45 of the part 4| or the carrier lugs 46 can also be fixed by screws 41, 48. The corners of the doorv are extraordinarily strenghtened by the said insets together with the rivets and screws. the locks on the door, the result is attained that the protecting edges 2l) can be carried straight through up to the top edge of the door so that they run uninterruptedly up to the lower edge 49 of the door frame.

As shown by Figs. 15 and 16, the corner corinection 50 can also be made Vas housing for runner rollers 5|. Such a corner connection may beY used both at the bottom and also at the top of they door. The rubber fillet or the like 2li is provided at the fixing side with a metallic holder 52. This is bent into a number of corrugations and the cross bars of the fillet 29 are held and clamped by the pocket-like parts 53 of the holders 52. To fasten the latter on the door section bar 2 as shown by Figs. 1 and 9,.a Vbolt 54 or hook 55 may be used at the bottom and a screw or the like 56 at the top. Y

According to Figs. 17-19, the two U-shaped bars 57, 58, are riveted together and projections 59 of the parts and 2 of the door pass through slots of the bar 51 on which they are bent over in the form of a clamp. This connection is to be used in particular for finishing the upper and By this method of fixing lower edges of the door. It can, however, also be used on the front and back edges of the door. If necessary, at such places which are less visible, separate parts of the door can be xed by rivets or the like directed towards the faces of the door. In this embodiment, the protecting edge 60 is made of closed box shape and nts by the fixing part in the H-shaped section bar 6|, the limbs of which also extend on both sides over the edges of the door. In this way, ugly abutment edges are avoided and in particular on metal plate doors an extraordinarily strong section is attained at the edge of the door. The bar 6| may, however, also be of U-shape, which if necessary also fits into a recess of the door. The xing of the bar 6| takes place by means of a metal llet 62 which, for example, is fitted at the bottom into a strong hook 33 and is fixed at the top by a screw or the like. It then bears under pressure against the bottom 64 of the protecting edge 63. After loosening the screw or the like, the unit formed by 6B, 62 can easily be removed from the edge of the door.

According to Fig. 20, the rubber llet or the like 35 is formed at the back into an enclosed hollow body or chamber 66 which is filled with compressed air, it being clamped behind projections 6l on the section bar 68 of the door.
